get_shopping_summary

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It describes output (total costs, item count, savings tips) but does not explicitly state that the tool is read-only or non-destructive. However, the name 'get' implies retrieval, and there are no parameters, so the risk is low. Lacks explicit behavioral disclosure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence in German with no wasted words. It is front-loaded with the main purpose and lists key outputs. Excellent conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given zero parameters and that an output schema exists (though not shown), the description sufficiently covers what the tool does: returns a summary of cart and wishlist with costs, item count, and savings tips. No additional context is needed for this simple tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist (0 parameters, 100% schema coverage). Baseline for no parameters is 4. The description does not need to add parameter info as there are none.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it provides a combined summary of the cart and wishlist, showing total costs, item count, and savings tips. This is a specific verb+resource that distinguishes it from siblings like manage_cart (individual management) and get_product_details (single product info).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for an overview of cart and wishlist, but does not explicitly say when to use or not to use alternatives, such as when to use manage_cart vs this summary. No when-not or exclusion criteria given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
